Eliza has had three fussy days/nights in a row, which is highly unusual for her. She’s usually a very peaceful, calm baby who is rather routine-oriented already. But for the last few days, she has been grumpy, refusing to nap, and crying as soon as we put her in her crib at night. After doing some reading, it seems like this might be a classic growth spurt. Apparently, they often happen around 3 weeks and again at 6 weeks. I remember the last one, and she was similarly fussy. It has been a rough few nights, but she should pass through it soon and hopefully return to her “old” self. On the positive side, she is smiling and cooing a lot more now. This is supposedly a big couple of weeks in terms of development; I can’t wait to see what each day brings. I just wish the nights would go back to normal!
